Objective:

Identify the social perception of key informants belonging to three communities of the Huasteca Potosina, on the participation of the climate and the possible negative effects of variability and CC, which they currently suffer at a local scale in their capitals and livelihoods.

Methodology:

Data from the "San Luis Potosí State Action Program for Climate Change" (PEACC-SLP prepared by the Autonomous University of SLP) was compared with data on the perception of change climate that have adult inhabitants of three communities of the Huasteca Potosina.

Results:

Among the results obtained, it stands out that the perception of the people agrees largely with the data of the PEACC-SLP in terms of changes in the patterns of temperature and precipitation in the last 40 years, as well as the change in land use as the main factor responsible for such changes at the local level.

Limitations:

It is considered necessary to carry out a broader investigation that allows knowing the social perception of variability and CC of the inhabitants of more communities in the region, as well as their adaptation and mitigation strategies that they are currently implementing to reduce their vulnerability.

Conclusions:

It is concluded that the PEACC-SLP does not reflect the strong negative impacts registered in the field that the inhabitants of these communities currently face, impacts that are increasing the vulnerability of the socio-ecological systems of the region. Does not show the adaptation and mitigation strategies that people implement for their survival and the continuity of their capitals and livelihoods.
